4.3 Release Notes: New UI & Approval Workflow

Teleport 4.3

This is a major Teleport release with a focus on new features, functionality, and bug fixes. It’s a substantial release and users can review 4.3 closed issues on Github for details of all items. We would love your feedback - please drop us a note, we’re always listening!

New Features

Web UI

Teleport 4.3 includes a completely redesigned Web UI. The new Web UI expands the management functionality of a Teleport cluster and the user experience of using Teleport to make it easier and simpler to use. Teleport’s new terminal provides a quick jumping-off point to access nodes and nodes on other clusters via the web.

Teleport’s Web UI now exposes Teleport’s Audit log, letting auditors and administrators view Teleport access events, SSH events, recording session, and enhanced session recording all in one view.

Teleport Plugins

Teleport 4.3 introduces four new plugins that work out of the box with Approval Workflow. These plugins allow you to automatically support role escalation with commonly used third party services. The built-in plugins are listed below.

Upgrade Notes

Always follow the recommended upgrade procedure to upgrade to this version.

New Signing Algorithm

If you’re upgrading an existing version of Teleport, you may want to consider rotating CA to SHA-256 or SHA-512 for RSA SSH certificate signatures. The previous default was SHA-1, which is now considered to be weak against brute-force attacks. SHA-1 certificate signatures are also no longer accepted by OpenSSH versions 8.2 and above. All new Teleport clusters will default to SHA-512 based signatures. To upgrade an existing cluster, set the following in your teleport.yaml:

    teleport:
        ca_signature_algo: "rsa-sha2-512"

Rotate the cluster CA, following these docs.

Web UI

Due to the number of changes included in the redesigned Web UI, some URLs and functionality have shifted. Refer to the following ticket for more details. #3580

Kubernetes Permissions

The minimum set of Kubernetes permissions that need to be granted to Teleport proxies has been updated. If you use the Kubernetes integration, please make sure that the ClusterRole used by the proxy has sufficient permissions.

Path prefix for etcd

The etcd backend now correctly uses the “prefix” config value when storing data. Upgrading from 4.2 to 4.3 will migrate the data as needed at startup. Make sure you follow our Teleport upgrade guidance. Note: If you use an etcd backend with a non-default prefix and need to downgrade from 4.3 to 4.2, you should backup Teleport data and restore it into the downgraded cluster.
